There is one difference. With journalists, restaurant reviewers, television critics, bloggers, usually you know who they are and there is a way to contact them. If you've been "Fact Checked" by some "Independent Fact Checker" on FB or Twitter for example, you have no way to know who they are, what their accuracy has been over time, no way to contact them, no way to look up other things that they have "Fact Checked" to see if they have an agenda or what their personal take on issues are. No way to know even what country they are in or what their expertise is in the field that you are discussing. No way to know if they are a world class expert on the issue or a kid just out of high school. If they have fact checked you, you have no way of knowing what their sources are. I've seen stuff "fact checked" where the fact checker was blatantly wrong and there was new more accurate information published in reputable journals such as Science, Nature, New England Journal of Medicine or the Lancet. How can you reach out to the "fact checker" to let them know that their information is out of date? You can't. What if their sources are more reliable? How do you know? A simple: "You've been fact checked and you are wrong" doesn't really mean anything as there is no way to know if this is truly correct. In fact, look at this debate that we are having right here, right now on
Additionally, for many issues that have been "fact checked", it is a matter of opinion and there is no clear answer. Much of the strife between the Democrats and Republicans has to do with seeing the world in very different ways and solving the world's problems with very different approaches. If you try to prove that one approach is factual and the other is not, both parties will be able to haul out and display plenty of qualified experts with perfectly valid scientific studies to back them up. The issue will never be solved by a panel of "experts". The point being that for many issues, there is no clear answer and a simple "fact check" will never be able to definitively resolve. "Fact Checkers" unlike those you mention purport to (and literally do) have the final say on any issue. With those you mention, there is always the understanding that some people might like different restaurants or television shows than the reviewer. The journalist understands that new facts may come to light.
So given all this, there is a big difference between journalists, reviewers, critics or even outright bloggers. "Independent Fact Checkers" are truly a creature unlike any other. They are the "Ministry of Truth" who whisper in their secret meetings: "Who controls the past controls the future. Who controls the present controls the past."
“The ideal set up by the Party was something huge, terrible, and glittering—a world of steel and concrete, of monstrous machines and terrifying weapons—a nation of warriors and fanatics, marching forward in perfect unity, all thinking the same thoughts and shouting the same slogans, perpetually working, fighting, triumphing, persecuting—three hundred million people all with the same face.”
